Effect of ICCP on bond performance and piezoresistive effect of carbon fiber bundles in cementitious matrix

The purpose of this study is to lay a foundation for developing a triple-functional system of impressed current cathodic protection, structural strengthening, and structural health monitoring (ICCP-SS-SHM) regarding carbon fabric reinforced cementitious matrix (CFRCM) material performance, and promote the utilization of seawater sea-sand resources to alleviate the shortage of freshwater river sand resources. In recent years, CFRCM, ICCP, and the piezoresistive effect have been widely studied in strengthening reinforced concrete structures, corrosion protection of steel reinforcement, and SHM, respectively. This study used two types of matrix materials: normal matrix (ISO standard sand) and seawater sea-sand matrix. The effect mechanism of the ICCP procedure on the bond performance degradation of CFRCM with the two types of matrix and the bond performance differences between them were investigated through carbon fiber bundle tensile tests and CFRCM bundle pull-out tests. Prediction formulas for bond performance were established based on the different charge densities, mechanical parameters, and resistance parameters, respectively. The piezoresistive effects of CFRCM with the two types of matrix after the ICCP procedure and the effect of ICCP on the piezoresistive effect were analyzed. The seawater sea-sand environment has a positive impact on delaying the degradation of CFRCM by ICCP.

High-efficiency, environment-friendly extraction of lithium from waste LAS glass-ceramics by roasting with KOH at low temperature

Recovering lithium from waste lithium aluminum silicate-based glass ceramics (LASGC) is one of the effective strategies to alleviate the shortage of lithium resources. Lithium extraction currently faces the problems of high energy consumption (>1000 °C) and secondary pollution. It is urgent to develop a high-efficiency, environment-friendly and low-temperature lithium extraction technology. In this work, KOH roasting combined with a water immersion strategy including lithium extraction, desilication, lithium precipitation, and the synthesis of silica hydroxyl intermediates was adopted to study the feasibility and advantages of lithium extraction from waste LASGC. When the roasting temperature is as low as 300 °C, the recovery rate of lithium can reach above 90 %, and the high-value conversion of solid waste in the whole process can be realized. In addition, the mechanism of lithium extraction was clarified through a series of characterizations. This work may provide a valuable reference for the efficient recovery and utilization of secondary lithium sources.

Assessment of water conservation and water intensification level based on AHP-fuzzy comprehensive evaluation model

Scientific evaluation of water conservation and water intensification level is an important prerequisite for addressing water resource shortage. In the current research, there are problems of confusing evaluation indicator systems and unscientific evaluation results. The paper first constructed the evaluation indicator systems of water conservation and water intensification based on the different connotations of the two, and then evaluated the utilization level of the two respectively by using AHP-fuzzy comprehensive evaluation model. The results indicated that from 2010 to 2022, the level of water conservation and water intensification in Zhengzhou both showed an upward trend, but the conservation level was higher than that of intensification. Therefore, promoting water intensification is the key to realize scientific water use in Zhengzhou in the future. Improving conservation level should prioritize the improvement of agricultural and domestic water use, while enhancing intensification level should prioritize the improvement of comprehensive and ecological water use. Separate evaluation of the two is more conducive to identifying weaknesses in their respective processes. Thus, more targeted and scientific improvement measures can be taken to enhance the level of urban water resource development and utilization.

Perceptions of and Experiences in a Clinical Externship Program During the COVID-19 Pandemic.

The clinical externship program for nursing students was developed and implemented during the COVID-19 pandemic at a multi-site healthcare organization.

The program incorporated a structured orientation, providing a mix of e-learning modules, in-person learning and shifts with an assigned preceptor. The program also included guidelines to define roles and responsibilities, ensuring safe integration of externs into the healthcare setting. A qualitative study design was employed using semi-structured interviews to explore the perceptions and experiences of the clinical externs (CEs), the extern mentor coordinators and the unit managers involved in the program. Five major themes emerged from the study, including the importance of orientation and the need for increased role clarity. The findings underscore the value of this opportunity both for nursing students as CEs and the broader healthcare system. This study provides valuable insights for nurse leaders aiming to develop or expand clinical externship programs, highlighting their potential to address health human resource challenges and enhance the preparedness and integration of nursing students into the healthcare workforce.

Discovering spatial co‐location patterns of urban facilities and their asymmetric characteristics

AbstractSpatial co‐location pattern (CP) mining can discover sets of geographical features frequently appearing in adjacent locations, which is valuable for comprehending the co‐occurrence relationship between features. However, due to the quantitative differences and heterogeneous distribution of features, the probabilities that features appear in each other's neighborhood are unequal, resulting in an asymmetric spatial pattern. Current studies have paid little attention to the asymmetric characteristics of CPs. Therefore, this study explores the CPs and their asymmetric relationships. Firstly, we adopt the weighted participation index to evaluate the frequency of global candidate CPs. Secondly, we employ an asymmetry index we developed and the local co‐location quotient to quantify the asymmetry intensity of CPs. The results indicate that the frequent CPs mainly comprise facilities related to the residents' daily lives. Investigating the asymmetric relationships and spatial associations among features in the CPs is significant for identifying resource shortages and rationally planning urban resources.

Integrating TQM into organizational culture for the success of the one Indonesian data (SDI) in the East Java

This study evaluates the implementation of Total Quality Management (TQM) in supporting the One Data Indonesia (SDI) policy at the East Java Provincial Communication and Information Agency (Kominfo). Employing a qualitative descriptive approach, the study well elaborates on challenges such as the lack of coordination between government agencies and the lack of regulatory support from the regional government. Despite these challenges, the implementation of TQM at the Communication and Information Agency has brought about well-described benefits, including increased data accuracy and relevance, as well as resource efficiency. However, obstacles such as the shortage of trained human resources and differences in data standards between agencies persist. The implementation of TQM has also fostered collaboration between government agencies and the private sector, enhancing the quality of public services. In conclusion, the implementation of TQM at the Communication and Information Agency supports the SDI policy by improving data service quality and strengthening organizational work culture. Further efforts in HR training and data standardization are necessary to optimize the SDI policy and improve public services.

Social acceptance and associated risks of geothermal energy development in East Africa: perspectives from geothermal energy developers

Abstract Social acceptance is a challenging aspect that affects the development of geothermal energy and such issues have been reported in many countries, such as Germany, Japan, Greece, and Kenya. In this study, we discuss the barriers to social acceptance and associated risks faced by geothermal energy developers in East Africa. We have conducted semi-structured interviews with international organizations (38.5%), public companies (38.5%), and private companies (23.1%). The interviews were qualitatively analysed using inductive content analysis. The key barriers identified by respondents were the lack of political, market, and community awareness; lack of local political support; lack of public funding; human resource shortages; involuntary resettlement; local cultural aspects; employment issues; and demographic change. The lack of awareness of geothermal energy affects public and private funding, and leads to negative risk perception by communities. Risks, such as air, soil, and water pollution, land acquisition, social exclusion, resource risks, and drilling and project costs, were considered important by our respondents. In this study, we emphasize the need for the following: raising awareness regarding geothermal energy; training professionals; implementing strong surface studies to reduce the risks associated with the exploration stage; and conducting environmental and social impact assessment reports to mitigate negative risks to local communities, while also ensuring their engagement and raising their awareness about the negative risks of geothermal energy.

'Beyond the Reach of Palliative Care': A Qualitative Study of Patient and Public Experiences and Anticipation of Death and Dying.

The demands and costs of health care resulting from increasingly ageing populations have become a major public health issue in the United Kingdom and other industrially developed nations. Concern with cost containment and shortage of resources has prompted a progressive shift in responsibility from state provision of care to individual patients and their families, and from the institutional setting of the hospital to the domestic home. Under the guise of choice and patient centredness, end-of-life care is framed within a discourse of the 'good death': free from distress and discomfort and accompanied by significant others in the preferred place, usually assumed to be home. The promotion of the 'good death' as a technical accomplishment enabled by pre-emptive discussion and advance care planning has sidelined recognition of the nature and significance of the pain and suffering involved in the experience of dying. There has been little research into the disparity between policy and professional assumptions and the lived reality of end of life. In this paper, we present findings from a qualitative study of how terminally ill patients, bereaved family members, and members of the public understand, anticipate, and experience death and dying. These findings contribute to an important and timely critique of the normative idealisation of death and dying in health policy and practice, and the need to attend closely to the real-world experiences of patients and the public as a prerequisite for identifying and remedying widespread shortcomings in end-of-life care.

Healthcare professionals endeavoured to cope with challenging work conditions, aiming ultimately to provide the best possible care to patients.

Dynamic Credible Spectrum Sharing Based on Smart Contract in Vehicular Networks

With the rapid development of the Internet of Vehicles (IoV), the demand for wireless spectrum resources has significantly increased. Dynamic spectrum sharing technology is regarded as a key solution to alleviate the shortage of spectrum resources. However, during the spectrum sharing process, security issues and a low utilization of the shared spectrum may arise. This study designs a consortium blockchain for trustworthy dynamic spectrum sharing in IoV environments. An improved asynchronous byzantine fault-tolerant algorithm is also designed to address the instability of signals in this scenario, and the allocation and management of spectrum resources between vehicles and base stations are further optimized using the Stackelberg game, ultimately deployed automatically through smart contracts. Simulation results show that our method not only significantly improves the system’s response time but also ensures communication quality and can maintain efficient operation under high network delay and complex scenarios.

Enabling Self-Practice of Digital Audio–Tactile Maps for Visually Impaired People by Large Language Models

Digital audio–tactile maps (DATMs) on touchscreen devices provide valuable opportunities for people who are visually impaired (PVIs) to explore the spatial environment for engaging in travel activities. Existing solutions for DATMs usually require extensive training for the PVIs to understand the feedback mechanism. Due to the shortage of human resources for training specialists, as well as PVIs’ desire for frequent practice to maintain their usage skills, it has become challenging to widely adopt DATMs in real life. This paper discusses the use of large language models (LLMs) to provide a verbal evaluation of the PVIs’ perception, which is crucial for the independent practice of DATM usage. A smartphone-based prototype providing DATMs of simple floor plans was developed for a preliminary investigation. The evaluation results have proven that the interaction with the LLM could help the participants better understand the DATMs’ content and could vividly replicate them by drawings.

Assembly mechanism and stability of zooplankton communities affected by China's south-to-north water diversion project

Water diversion can effectively alleviate water resource shortages and improve water environmental conditions, while also causing unknown ecological consequences, in particular, the assembly mechanism of zooplankton communities in the affected areas will become more complex after long-term water transfer. Taking Nansi Lake, the second largest impounded lake along the eastern route of China's South to North Water Diversion Project (SNWDP), as an example, the composition and diversity of zooplankton communities in the lake area and estuaries during the water diversion period (WDP) and non-water diversion period (NWDP) were studied. The potential assembly process of zooplankton communities was further explored, and the stability of communities in different regions during different periods was compared. The related results indicated that the changes in water quality conditions induced by water diversion had a relatively weak impact on the zooplankton communities. In the assembly mechanism of zooplankton communities, stochastic process played a more important role during both WDP or NWDP, and the proportion of deterministic process was relatively higher during NWDP, which may be related to the greater role of total nitrogen (TN) in the assembly of the zooplankton communities. The network analysis and cohesion calculation results showed that the stability of the zooplankton communities in the lake area sites was higher than that in the estuary sites, and the stability during NWDP was higher than that during WDP. In sum, the stability of zooplankton communities displayed a degree of change affected by water diversion activities, but the community assembly was not significantly influenced by the water quality fluctuations after about relatively long-term water diversion. This study provides an in-depth understanding of the ecological effects of water diversion on the biological communities in the affected lake, which is beneficial to the management and regulation of long-term water diversion projects.

Identifying barriers and good practices for implementing circular economy principles in small and medium enterprises

AbstractRecently, the new industrial paradigm of circular economy (CE) has acquired increasing attention. In a CE, the value of materials is preserved by keeping them for as long as possible in the economic system, overcoming the “traditional” linear model (take‐waste‐disposal). Despite its benefits in terms of sustainability, there are still numerous barriers to the implementation of CE principles for companies, and specifically, small and medium enterprises (SMEs) find it difficult to integrate CE principles within their business models due to a shortage of resources. Hence, a qualitative multiple‐case study involving four Italian companies implementing CE principles is conducted. The findings contribute to the development of CE principles in SMEs by proposing good practices, such as encouraging SMEs to engage in research projects to secure initial investments, expanding suppliers' networks to reduce the risk of limited by‐product availability, and implementing organizational training on CE to enhance employees' awareness and skills.

Nephrological care in Ukraine during wartime: challenges and innovations

The war in Ukraine has profoundly impacted the provision of nephrological care, presenting numerous challenges while also driving significant innovations. This study aims to analyze the availability and quality of nephrological care in Ukraine during wartime, focusing on chronic kidney disease stages 1–5D/T. The conflict has caused population displacement, restricted access to treatment, and disrupted healthcare logistics, adversely affecting nephrological care. Despite these challenges, the healthcare community has adapted through the implementation of virtual nephrology, incremental and extended dialysis regimens, and increased use of new therapy approaches. The war led to a decrease in the population and migration of medical personnel, particularly from southeastern to western Ukraine, causing staffing imbalances that were gradually addressed. Technological innovations, such as digital nephrobiopsy with immunohistochemical analysis and the use of cloud-based technology, allowed for rapid and remote diagnosis. Virtual healthcare and remote consultations ensured continuity of care, while kidney transplantation activities saw a notable increase, facilitated by advanced techniques and international aid. Despite initial logistical challenges and resource shortages, the resilience and adaptability of the Ukrainian nephrological care system have been evident. This study underscores the importance of robust contingency planning, international collaboration, and the adoption of innovative solutions to maintain healthcare delivery in conflict zones. The findings offer valuable insights into managing nephrological care under extreme conditions and highlight the potential for these innovations to improve care delivery globally.

Implementation of Perkasal Policy Number 38 of 2021 Regarding the Acceptance of Cadets and Cadets of the AL Navy Academy in a Gender Perspective

This research will examine the implementation of Policy Perkasal Number 38 of 2021 regarding the Admission of Cadets at the Indonesian Navy Academy (Akademi TNI AL) from a gender perspective. It will also explore the challenges faced in the implementation and efforts to overcome these challenges within the framework of Policy Perkasal Number 38 of 2021. The research will focus on the selection process of male and female cadets according to the mentioned policy. The research methodology employed in this study is descriptive qualitative research. Data collection methods include interviews, observations, and literature reviews. The theoretical framework used in this research is the policy implementation theory according to Mazmanian and Paul A. Sabatier. The findings of the research indicate that the implementation of this policy has not yet achieved gender equality and justice. Technical constraints and societal views that do not support equality remain significant challenges. The policy lacks clear objectives to prevent gender discrimination. Socio-economic conditions in Indonesia also influence the acceptance of male and female cadets. Factors affecting policy implementation involve ambiguity in gender-based quotas, lack of socialization, limited involvement of female soldiers in structural positions, high aspirations to enter non-military higher education institutions, decreasing interest in becoming civil servants, minimal facilities, heavy curriculum burdens, and a shortage of human resources. Recommendations include establishing clear gender-based admission quotas, intensifying socialization efforts related to Policy Perkasal Number 38 of 2021, increasing the involvement of female soldiers in structural positions, adjusting the military education concept to the social context of women, and improving training facilities for prospective Indonesian Navy soldiers.

Кризисы модернизации 1990-х годов в контексте исторических циклов России

The article compares the reckless socio-political dynamics in Russia in the 1990s, manifested in a series of crises and turning events, with the concept of mechanisms of the Russian historical cycles. The paper lists the main stages of dynamics — complexes of interrelated events that change the balance of power, structural conditions and the direction of subsequent processes. The author also lists the main actors and social groups involved in the political dynamics of that time period: supreme power, reformers, insiders, oligarchs, representatives of special services, “pro-soviet” and democratic opposition, urban educated class, workers and miners’ movements, “ordinary people”. The author concludes that the rapid sweeping changes in the politics of the 1990s took place, as they did before, in the parametric space with the axes of “state success” and “freedom”. Transitions occurred between the phases that were typical for much longer cycles of the Russian historical past — “crisis”, “liberalization”, “authoritarian rollback”, “state collapse”, “military-political triumph”. At the same time, the mechanism of the general democratic backsliding trend and the growth of authoritarian tendencies calls for clarification. The authors propose a phase model that explains this change through the patterns of response strategies of the supreme power to challenges and threats under different conditions. Weakness and failures of the state policy coupled with a shortage of resources led to mass disillusionment, delegitimization of the supreme power and reform policy, which manifested itself in elections and inspired the adherents of the restoration. The increase in the corresponding threats placed a premium on administrative and violent measures. Once sufficient resources were accumulated, those measures were becoming successful and received positive reinforcement. With each crisis, the supreme power took an upper hand, while the collegial separation of powers was reduced, and the reforms lost their original focus on economic freedom, the rise of small and medium-sized businesses, and the growth of democracy. As a result, the opportunities for the political modernization were missed, giving way to the authoritarian trends.

Electrothermal-assisted all-weather solar steam generator based on hydrogel implantation strategy

Using solar energy to treat sewage is a feasible scheme to alleviate the shortage of water resources and reduce carbon emissions. However, the fluctuation of sunlight intensity poses a great challenge to the stability of the treatment process, which hinders its application in the actual water treatment scene. Herein, based on the adhesion of hydrogel, an electrothermal-assisted all-weather solar steam generator with sandwich structure was synthesized through hydrogel implantation strategy, in which polyacrylamide hydrogel with thermal grease-modified heating wires was implanted as the middle heat conduction layer, the photothermal evaporation layer as the upper layer and the waste heat evaporation layer as the bottom layer. The electrothermal assisted solar evaporator (EASE) perfectly achieves the superposition of photothermal and electrothermal effects, and can achieve high interfacial water evaporation performance under extremely low auxiliary working voltage. Applying a low voltage of 2 V to both ends of the evaporator can achieve a high evaporation rate of 4.58 kg m−2h−1 under 1 solar irradiation, which is similar to the sum of the evaporation rate under only 1 solar illumination (2.22 kg m−2h−1) and a 2 V voltage input (2.26 kg m−2h−1). More interestingly, the suitable thickness of the hydrogel layer not only ensures the transfer of heat between layers, but also weakens the heat loss caused by the water flow effect. The implantation strategy ensures the stability of the water structure and inhibits the hydrogen reaction of electrolytic water in the electrothermal process. This work provides an important theoretical and practical reference for the preparation of all-weather solar interface water purification equipment.
